Remove DevOps Tools Comparison PDFs

Why is this change being made?

This MR removes all the dated DevOps Comparison PDFs located in /sites/marketing/devops-tools/pdfs. These PDFs are not linked to from the DevOps Tools Comparison pages and will not be used going forward as stated by @mskumar.

This MR also removes html pages that were generated by the PDFs and a proxy in /sites/marketing/config.rb. For example, the following two resources existed for Jenkin which have been removed:

    - /devops-tools/pdfs/jenkins-vs-gitlab.html
    - /devops-tools/pdfs/jenkins-vs-gitlab.pdf

This MR also adds redirects for all the PDF and HTML pages that have been removed. The list of PDF and HTML pages that are removed are listed below. Removing these pages from our build with speed up the pipelines as well =)
